Severnaya Dvina River

Ichthyofauna from the Key Sections of the Middle and Upper Permian of Eastern Europe: Complexes and Zonal Scale. Paper 1: Basin of the Severnaya Dvina River

The paper presents new material on ichthyofauna from the key section of the Middle and Upper Permian of the Severnaya Dvina River. Stratigraphic distributions of fish taxa are traced back and significant changes to the fish complexes are proposed. A modified paleoichthyological zonal scheme of the region is proposed as a result.
